[{"type":"text","content":" Discovers New Mineralization Exposed by Road Cuts Appoints New Director VANCOUVER, British Columbia, Feb. 21, 2018 (GLOBE NEWSWIRE) -- Centenera Mining Corporation (“Centenera” or the “Company”) - (TSXV:CT) (OTCQB:CTMIF) reports that drilling has begun at the Esperanza Copper-Gold Project, San Juan Province, Argentina. Centenera received a drill permit in late 2017 (previous news release November 20, 2017) and immediately mobilized heavy equipment to begin refurbishing approximately 40km of road access. This work was completed in late December at which time the drill camp and related infrastructure was delivered in preparation for drilling in early January 2018. Unseasonal storms and flash flooding in January meant that road repairs and new drill access roads had to be constructed, causing a short delay to the drill start. The required earthworks have exposed significant new mineralization at surface, expanding the previously known footprint of mineralization to the southeast. New Mineralization Discovered In the process of construction of new road access to the first drill platform, new mineralization was exposed at surface, in an area previously indicated as being underlain by unmineralized basement gabbro complex (Figure 1). The exposed mineralization is hosted in intensely altered rock interpreted to be part of the highly-prospective Canyon Stock which now appears to extend significantly further to the southeast than previously known. The mineralized rock contains dense pyrite veinlets with supergene sulphides over approximately 75m. Moving further southeast an additional 20m of slightly less mineralized rock has been observed. True thickness of mineralization is not known at this time. Mapping and sampling will be completed over the coming weeks. Esperanza Copper-Gold Porphyry Highlights The outcropping copper-gold porphyry mineralization at Esperanza was first drill-tested in 2006-2007 by 7 drill holes totalling 2,011 metres. All drill holes intersected significant copper-gold mineralization (Figure 1). Drilling highlights include: Best intersection is 353.1m1 from surface, grading 0.35% copper and 0.18 g/t gold (0.49% copper equivalent2) including 243.1m1 grading 0.40% copper and 0.21 g/t gold (0.57% copper equivalent2) Mineralization is outcropping ...
